To all whom z't may concern."

Be it known that I, ARTHUR J. Evans, a citizen of thelUnited States, residing at Chicago, in the county. of Cook and State of Illinois, have invented certain new and useful Improvements in Pasteboard-Box-Making Machines, of which the following is a specification.

My invention pertains to machines'ror making boxes of the pasteboard, cardboard,

' or similartype, such for example, as are garments, suits of clothes,

frequently used for theaccommodation of etc., but it is, nevertheless, to be understood that the invention is not limited or restricted to the style, size, or shape of the box, or the purpose 4for which 1t may be employed. n `v @ne of the leading objects of the inven- ,l tion iSv-the provision of a simple machineot ,this general character which will be ecothere is but little,

nomical to construct, which will so-fold the blanks and form the corner portions that a box of considerable strength will be produced, with-strong corners able to withstand all ordinary usages without breaking or tearing apart. 'Ihe type oit .box produced also readily yields itself condition if desired.

.A further feature 0I the invention re-^ scribed in detail below and illustrated in the' accompanying'drawings, throughout the ya- Y a rlous views of which like referencel characters refer tothe vSame parts.

Fig. 8 is a view more or less'diagrammatic of the means adjustablyconnecting and as-v sociating together the four corner of the structure set forth: v

Fig. 9 is a fragmentary face view of one of the pressers, and

Figs. 10 to 14 inclusive show the steps of folding up one corner portion of a pasteboard blank.

'Ihe `it'our corner portions. of the machine are substantially alike, ,of the construction and operation of one will sufce for all, `it being understood iniportions tially that the appliance has four forms or` blocks one at each corner, around which the corresponding parts of the box are made simultaneously from a flat pasteboard vor similar blank, and that these forms and their associated folding and pressing mechanisms are readily adjustable toward and from one another, whereby boxes of dillerent sizes may be readily produced.

This single corner portion of the appliance comprises a frame 20 on which is bolted a casting comprising a base-plate 21, paralrammed inar. a. rain.

perspectively l so that a description lel upright-walls 22, 23, and a connectingwall 24k. At the junction of walls 22 and 2li and integral therewith, is a depending form or block 25 substantially square in cross-sec tion, and it is around this that one corner of the box is tobe made by means of suitablei folding andv pressing elements. The relation of the four forms one another is shown in a general way and diagrammatically in Fig. 8. The pasteboard yblank 26 but not exactly, beneath these four forms by any approved means, not shown, and its four corner ortions are acted-upon at the same time. uch

of substantially,

dat blank, a corner section only of which isl 25, 25a, 25h, 25, to

rectangular shape, is fed indicated'in Fig. 10, comprises a central rectangular bart 27 of a size to constitute the box bottom or head, depending upon whether a box body or box cover 1s being made, surrounded by side and endiaps 28 and 29adapted to be folded up to form on lines 30 and 31 respectively to constitute the side and end walls of the box.. At eachcorner this blank is notched at`32 removing a small, substantially-square, waste piece, and itis slit diagonally at 33, separating the adjoining tabs 34 and 35 integral with the side 'and end flaps 28 and 29 and adapted to vbe bent up on lines 36 and 37 respectively.

Before'being bent to form the corner, .the top surface of Ytab 35 and an adjoiningarea of the end fiap 29 corresponding inszeand shape tothe companion tab 34 is coated with esive tohold the partsfto4`- f folding up against their outer faces.

Itis, of course, desirable to hold the blank 4 up against'the bottomface of theform durling theffol'ding operation, and ,to perform thls function, I provide a bent arm 38 of the peculiar shape shown in the various figures, andv fulcrumed at`39, the arm having a free, elevated, flat end 40adapted tocoperate with lthe under face ofy the form, the arm being otherwise: bent to escape 'coniict with," other portionsof the machine. Such hold ngkarm or finger is operated by means of a 41 pivotedthereto at 42and to `a projection 43S extended from a leverr 44 fulcrumed--atl 45 on another lever -46'adapted to oscillatel on -a fixed fulcrum 47. The lower end of lever .44 isbifurcated at 48 to straddle 'shaft49, theV latter being :provided with an oscillatory, rectangular, guide block I 5() arm 441'l1aving asan actuating means' a ro er, 51 traveling in a cam groove 52I cut'in Y. asshown. Obviously,sfrom an understandf r111g of this construct1on, it will be apparent 50 y that thislgcam,' `through 4`-the connections y'Assuming' v form and .its corner'portion held against its under surface by the end 40 of the arm-38,

the foldii'igk operation will take place sub` stantially asJ follows., and the mechanism indicated. 'u

It' is lirstnecessarv toffold orbend un thev ab e4` ahnte-vialey 36V `and 'this is brought about Abymeans of abent ear'or folderw54 v(Figs. 4, 6,1and 7 ),v rockingly mounted `tov vturn v-1I 1 thebearmgs 5 5 and 56.A This folder `iFig. 11'.

v The next step in the operation is to simulthat is beneath v 54 is of the peculiar configuration shown in Fig. 7, and has rigid therewith a pinionv 57, the teeth of which are in mesh with those of a. short rack 58 mounted on the end of a curved arm 59 fulcrumed at 60 and provided about midway of its length with an extension 61 (Fig. 4), carrying a roller 62 accommodated inf a cam groove 63 of a cam 64 (Fig. 2) `on a shaft. 65 driven from the companion shaft 49 by means of intermeshing bevel gears 66 and 67, the shaft 65 being mounted 'to'rotate in suitable bearings 68, 69, as shownk in Fig. 2.

By a V:relatively-quick movement the folder 54 'bends the tab 34 along the line 36 through ran angle of approximately 180, that is,

over .on to the ap 28, and then recedes, permitting such tab to spring back more or less to substantially the position shown in taneously bend up .the side flap' 28 on the line 30 and the tab 35 on the line 37, these (two lines being in register and the two parts 28 and 35Nbefore bending being in the same horizontal plane. This folding is laccomplished by means of a bender comprising two parts 70 and 71 separated more or less by a gap or recess bounded by the edges 72, 73, 74, and 75, (Fig. 7), which space in the unoperated position of the bender accommodates the `folder-54 in a portion of its operating and supporting mechanism, the same recess being also employed to permit the pressing mechanism described hereinafter to cooperate with the blank and form. Bender 70, 1, constitutes a fiat plate pivoted or hinged at 7 6, 77, adjacent to the form 25,

but belowit.

u This double folder 70, 71, is connected by 105 means ofa link l'78 below it to one substantially-horizontal arm 79 of a bell-crank fulcruied at 80 and having a dependin `arm Slequipped with a roller 82 receive in a camegroove 83 of the drive gear 53. A 110 At about thel same time that the side iap 28 and the ntab 35 -begin to swing upwardly,

the end ap 29 is also folded upwardly and the tab 35 by engaging the previously folded .tab 34 is guided as shown in Figs. 12 and 13 115 to the outside of the iap 28 as illustrated in Fig. 14, the endiap 29 coming up thus against the face of Ithe. form and the outer face-of the tab .34. Such bending or folding of the end Hap 29 and its associated tab 120 35 is accomplished by meansA of a folder 84 of the peculiartapered formation shown in Fig. 7 and hinged or fulcrumed'at 85, 85.

It is operated fromy beneath by a link 86 piv'- oted to a projectionfon its under face and also pivoted to one arm 87 of a bell-crank fulcrumed at 88, the companion arm 89 having a roller' 90 traveling in a cam groove 91 of cam 92 also fixed to the shaft 65, (Fi 2).

T he flatvblank having been folded or ent remesa yfolders or benders -described above, but

rather by separate pressing instrumentalities.

To press the tab 35,-coated on its inner surface with adhesive, against the outer face of the side Hap 28, l[ provide an upright lever 93, (Fig. 3), fulcrumed at 94. and shaped to form a presser 95 as shown in fFig.y 9 and corresponding to the configuration of the tab 35, being tapered or .at its lower of the shape shown in Fig. 2, (which isl beveled at its lowerportion.V This presser 95 is enabled to co-act with the t-ab 35 by reason of the space between the companion benders 70 and 71, thus giving access to the tab by the presser 95 for the performance of its function. Lever 93 is actuated by a. toggle 96, 97, the link 97 being fulcrumed at 98 and the knuckle pin 99 of the toggle being connected by a link 100 to a lever 101 fulcrumed at 102 and equipped with a roller 103 traveling in. a cam groove 104 in cam 105 on shaft 49. 1t is preferable to make the link 100 somewhat yielding to compensate for diderence's in the thickness of the pasteboard and it may be provided with any one of the usual spring constructions' for this purpose.

lft is also desirable or necessary to press the v glue -coated end flap 29 against the outer face of the inner flap 34 which it overlies, and against the corresponding face of the form, and to bring about this result the mechanism is provided with-another lever 106, (Fig. 4), fulcrumed at 107 and shaped end to constitute a presser 108 substantially the saine shape as the presser 95), and corresponding in confguratlon to the tab 34, it being noted, as is illustrated in Fig. 7, -that the lbender 84 is beveled or cut away on the line 109 so that the presser may perform its work without interference with such bender' or folder. Presser 108 is actuated by a toggle 110, 111, the link portion 111 being fulcrumed on a stationary shaft 112, the toggle being operated by a link 113, preferably some` kind of a spring yielding link, pivoted at its lower end to a Y lever 114 hinged or fulcrumed at 115 and actuated by a roller 116 located in a cam groove 117 of cam 64 on shaft 65.

'llhe parts are so shaped, arranged, vand interconnected, that the folding operation `is completed, whereupon the two pressers come into action and secure a very rm and uniformpressure on the overlapped surfaces jee of the parts 28 and 35 and 29 and 34 to cause their complete adhesion by reason of the glue previously applied to their surfaces. By the employment of toggles, these .pressers can be made adequate for all purposes, it being understood that the blank folders or benders are so shaped, as illustrated, that when they are rocked up toward the form, they do not overlap, the outer surfaceof flap 28 covered by the tab 35, nor the outer surface of flap 29 beneath which the tab 34 is positioned. Or, stated somewhat differently, these Ifolders or benders are properly recessed to .permit the pressers to reach the work and fulfil their functions without interference or conflict with thebenders or folders, and vice versa.

The box having been thus completed, it is discharged or stripped from the 'four forms simultaneously by reason of an ejecting mechanism associated with each. Each of such devices comprises a right-angle stripper 118 engaging the two adjacent surfaces rod 119 guided in bearings 120 and 121 and manipulated automatically by a link 122, (Fig. 3), connected to a collar 123 on the rod and also connected to the rock lever 46. Ordinarily this stripper or discharge device is. elevated to permit the folding operation, and it then descends at the proper time to discharge the box.

The appliance may be driven or operated by any approved means, but in the device illustrated this is brought about by a pinion 124 on a drive-shaft 125, (Fig. 3), the pinion meshing with the teeth of the ylarge gear 53 on shaft 49 and, of course, the rotation of this shaft is carried to the shaft 65 through the coperating bevel gears 67 and 66.

\ llt is desirable in an apparatus of this kind to Lmake it adjustable so that it can readily manufacture 'boites of dierent sizes, and this part of the invention is shown diagrammatically in Fig. 8, wherein the four forms and their operating mechanisms have been given the general reference characters A. B, C, and D.

The mechanisms A and B, and C and D,

are adjustable toward and from one another '115 by means of shafts 126, 126, provided with operating handles 127, 127, and having screw-threaded connections 128 with the four devices, and in order to permit the gears 124 to `remain in operative association with their shafts 125, they remain slidable thereon, the shafts being equipped with f keyways 129 in the usual way, which have mechanisms by reason of the yoke construciso . described.

shaft 133 providedwith a suitable keyway.

mav be employed for turning any one of these shafts 135, whereupon, of course, the

vother shaft will be rotated in like manner and corresponding amounts.`

-While I have herein described withA Some degree of particularity one desirable embodiment of the invention, it is to be understood that it is not limited and restricted to the'precise and exact details of construction because these may be varied within wide limits without departure from the substance of the invention and without the sacrifice of any of its substantial beneiits and advantages.

For example, 1t is not absolutely neces,

sary under all circumstances that the tab 34 shall be preliminarily bentuup and conseguently, thisportion of the mechanism may,

1n some instances be omitted. It will furthermore be observed that either oneVl of the tabs 34 or 35 may be omitted and a box of satisfactory character produced, though possibly not one quite as strong as where both tabs are used.
